“…Given the limitations of the approach demonstrated here as compared to obtaining 3D information via tomography [3,7], we anticipate the application of this 3D imaging method especially for weakly absorbing samples, e.g. for research in life science, in situations where the acquisition of many projection images is not possible.…”

“…In addition, the off-axis geometry of the reference wave source from the object effectively spatially separates the twin-images occurring in the hologram reconstruction. Due to these advantages and its simple experimental design, FTH with X-rays is routinely applied in numerous experiments such as relating to imaging nanomagnetic structures [26][27][28][29][30][31][32] or biological specimen [7,13,21,33].…”

“…A 3D reconstruction of the object can then be retrieved in a tomographic approach by utilizing a set of projection images from different angular perspectives. These 2-dimensional (2D) projection images can be obtained by different imaging methods such as X-ray full-field microscopy [3], coherent diffraction imaging (CDI) [4,5], ptychography [6] or holography [7]. CDI alternatively allows reconstructing a 3D model of the specimen from a 3D reciprocal-space data set that again was composed out of many 2D diffraction patterns taken from different sample orientations [8,9].…”

Abstract: We demonstrate how information about the three-dimensional structure of an object can be extracted from a single Fourier-transform Xray hologram. In contrast to lens-based 3D imaging approaches that provide depth information of a specimen utilizing several images from different angles or via adjusting the focus to different depths, our method capitalizes on the use of the holographically encoded phase and amplitude information of the object's wavefield. It enables single-shot measurements of 3D objects at coherent X-ray sources. As the ratio of longitudinal resolution over transverse resolution scales proportional to the diameter of the reference beam aperture over the X-ray wavelength, we expect the approach to be particularly useful in the extreme ultraviolet and soft-X-ray regime.

Different X-ray holography methods are reviewed and their features and capabilities discussed. Particular attention is paid to the fluorescence holography method, which allows obtaining three-dimensional local structure images of ordered objects with atomic resolution. Using concrete examples, it is proved that X-ray holography is a unique nondestructive structural characterization method for a wide class of objects.Physics ± Uspekhi 58 (4) 365 ± 383 (2015) #2015 Uspekhi Fizicheskikh Nauk, Russian Academy of Sciences Contents 1.

“…Consequently, the transmission through the circular reference aperture is already blocked at tilt angles of approximately arctan 0.2 11 ( ) »°, resulting in an accessible angular range which is too small for tomography. Nevertheless, it is possible to combine soft-x-ray FTH with tomography using an optically inverted sample design: the reference aperture is replaced by a small absorber or scatterer, located on a transparent support membrane in close proximity to the object to be imaged [8]. While this open-membrane approach allows for sample rotation and retains the advantages of monolithically coupling the sources of object and reference waves, the large amount of directly transmitted light creates a large background intensity in the hologram.…”

We explore tomographic mask-based Fourier transform x-ray holography with respect to the use of a thin slit as a reference wave source. This imaging technique exclusively uses the interference between the waves scattered by the object and the slit simplifying the experimental realization and ensuring high data quality. Furthermore, we introduce a second reference slit to rotate the sample around a second axis and to record a dual-axes tomogram. Compared to a single-axis tomogram, the reconstruction artifacts are decreased in accordance with the reduced missing data wedge. Two demonstration experiments are performed where test structures are imaged with a lateral resolution below 100 nm.
